Understanding risk

Risk of stroke after TIA / minor stroke

The red men represent people having strokes. 10 people will have a stroke in the 7 days after a TIA – a 10% risk. The daily risk of stroke falls over the next few months. About another 5 people (5%) will have a stroke between 7 and 30 days, another 5% between 30 days and 90 days and another 5% between 90 days and the end of the first year. Therefore, 25 (25%) will have a stroke over the first year but most occur in the early period.
